I started my PhD in September 2012 with Dr. C.F.M. de Lange after completing a Master's degree investigating the nutrient retention in entire male pigs immunized against gonadotropin-releasing hormone. The main focus of my PhD program is determining lysine utilization efficiency for milk protein synthesis by the mammary gland in sows fed varying levels of crude protein. High levels of crude protein (i.e. non-essential amino acids) may negatively influence lysine utilization by the mammary gland, in addition to increasing nitrogen excretion into the environment. I am working collaboratively with Dr. N. Trottier at Michigan State University to meet the research objectives.
